A tie or truss rod 27 connects each bolt 25 with the corresponding sideof theloop or attachment element 16, and, accordingly, the outer end ofeach such rod has a loop 28 receiving the correlated bolt 25, the innerend of the rod being screw threaded, bent to pass through a hole'in theside of member 16, and supplied with nuts 29 and 30 disposed on oppositesides of and bearing against the opposite surfaces of the correspondingpart of the loop element.

Directly above the pipe 10, the member 11 has an upstanding strutportion 31 notched or recessed at its upper end to accommodate thecentral portion of a bent or cambered truss vor tie rod 32 having loopends encircling the upper bolts 21, 21 of the two collars 20, 20. a

,. In similar manner, below the pipe 10,

the part 11 has a depending strut portion 33 recessed at its lower endto receive a lower truss or tie rod 34, looped at its opposite ends tofit over the lower bolts 21,

21 of the pair of companion collars.

Member 11 also has a pair of rearwardlyextended, spaced, horizontal ears35, 35 equipped with a bolt 36, and a cambered rod 37 extends. betweensuch ears bearing on the outer faceofthe bolt, the ends of the rodhaving loops or eyes coacting with the bolts 26, 26 of the two collars,the rear ends of the ears 35 being apertured at 38 for the attachment ofthe central or middle agricultural implement as by means of the usualclevis.

Thusthe middle portion of the pipe or tube 10 is trussed and stiflenedin four directions, portions of the truss structure affording convenientmeans for the connections with the tractor and one of the seeders,barrows, or the like. 7

' Just beyond the two truss collars specified, the pipe is supplied witha pair of sleeves 39, 39 with enlarged outer ends 40 bolted at llthrough the pipethusefi'ectively preventing their displacement ordislodgment.

Each such sleeve forms a bearing for a ground or carrying wheel 42'desirably, vthough not necessarily, of the steel tire and steel spoketype, each such wheel being prevented from axial movement longitudtnally of the pipe by coaction with the adjacent collar and theenlargement of the sleeve. 1

At its extremeends, or elsewhere if preferred, the hitch is fitted withforgings 43 bolted thereto at 4A and formed or shaped fort connectionwith the other agricultural tools.

It Will be perceived, therefore, that the draft appliance. is adequatelytrussed and strengthened between the carrying or ground Wheels, which.truss structure acts also to stiffen the parts of the main pipe memberbeyond the Wheels to perform their functions without danger ofbending orc0-llapse by reason of the strains and stremes to which they are put.

It will be observed that the long pipe or tube forms the backbone of thestructure, that some of the attachments of the draft members are madesubstantially directly with the truss structures, and that the wheelsare mounted directly on the pipe revolving about the axis oflthe latter.

Such I a structure embodies maximum strength for the amountof metalemployed, the appliance as a whole including relatively few parts soassociatedand connected together as to secure great rigidity and strainresisting qualities.-

The invention is not limited and restricted to the precise and exactdetails of construction illustrated and described, but rather stantialor material benefits and advantages.

I claim v 1. In an appliance of the character described, the combinationof a substantiallystraight metal pipe constituting a draftbeam, a strutmember, fastened to the middle of said pipe and having aforwardlyextended socket, a forwardly-projecting draw-bar pipe securedin said socket, a pair,

of collars fastened to said pipe on opposite sides of and remote fromsaid strut member, truss rods connected at their ends to said collarsand coactingwith the struts of said member, tie rods connecting saidcollars to the front end portion of said forwardly-extended draw-barpipe, sleeves on said pipe outwardly beyond said collars but remote fromthe ends of the main pipe, carrying wheels revoluble about the axis ofsaid draft-beam pipe on said sleeves, means permitting the attachment ofa traction appliance to the front end :of said draw-bar pipe, and meanspermitting the attachment of agricultural implements to said mainbeampipe.

2. In an appliance of the characterjdescribed, the combination of ametal draftbeam pipe, a strut member fastened to the central partof'said pipe, a pair of collars secured to said pipe remote from itsends, top, bottom, and rear truss-rods fastened to said collars andbearing at their middle portions on strut parts of 'saidmember, saidstrut member havinga forwardly extended socket, a draw-bar pipe'havingits rear end tening said loop element to said draw-bar pipe, tie-rodsfastened to said collars and each havin a bent threaded end extendedthrough a hole in thefcorresponding side 5 ofsaid loop element, nuts onsaid threaded ends securing them to said loop element, means to attach acentral agricultural implement to said strut-member, sleeves on saiddraft-beam pi eoutwardly beyond said 10 collars but inwar y remote fromthe ends said sleeves aboutthe axisof said pipe and prevented fromlongitudinal movement on y the latter by cooperation with said collarsand enlarged portions of said sleeves, and means to attach agriculturalimplements to, said main-beam pipe outwardly beyond said wheels.
